UPDATE: EMBATTLED 2Day FM radio hosts Michael Christian and Mel Greig have recorded tell-all interviews with Channels Seven and Nine to air tonight.

Speculation that the duo have chosen to share their side of the international scandal with Channel Nine was sparked earlier today when host Tracy Grimshaw and executive producer Grant Williams were seen striding confidently through 2Day FM's inner-city headquarters.

The program then confirmed the interview on their twitter account saying: "First interview with the #2dayfm djs just recorded with @TracyGrimshaw. It's raw & emotional. The full uncut interview at 6.30 tonight #aca9".

Christian and Greig will make their first public appearance in what is an unpaid interview with ACA. It is understood they have also recorded an interview with Channel Seven, which will air on Today Tonight.

Speaking for the first time to ACA about the prank which fooled the nurse into thinking she had been speaking with Queen Elizabeth over the Duchess of Cambridge's morning sickness, the pair said they are thinking of Ms Saldanha's family.

"And I remember my first question was, was she a mother? I hope they're OK, I really do," Greig said.

"...there's not a minute that goes by where we don't think about her family and what they must be going through and the thought we may have played a part in that is gutwrenching," Greig added.

Earlier reports suggested the duo had also filmed an interview for Channel 10's The Project, but one of the show's producers Tom Whitty tweeted that the pair were too distressed to be interviewed.

"We are however interviewing Rhys Holleran, CEO of Southern Cross Austereo, about the story," he added in a later tweet.

Meanwhile staff at Southern Cross Austereo have all but shut-down in the lead-up to the interview, with 2Day FM programming boss Guy Dobson and interim media manager Sandy Kaye failing to return calls today.

The executive producer of the Hot 30 Countdown, Emily Mills, appears to have deleted her Twitter account and LinkedIn account and is also not contactable.

A close family member reportedly told the Times of India that the mother of the nurse who killed herself after 2Day FM radio hosts fooled her into thinking she had been speaking with Queen Elizabeth over the Duchess of Cambridge's morning sickness was suffering from heart problems and was under sedation.

"We are in a difficult situation and don't know how to convey the sad news to her," the family member was quoted by the Times as saying.

"He's very angry about all the proceedings, not only about the DJs but all the handling of the situation in the hospital. He feels very angry about the hospital management. He's been full of stress about the whole thing. It's not a very nice time," Benedict's friend Stephen Almeida told the paper.

However their station 2Day FM and parent company Austereo are under siege with internet hoaxers tricking Facebook users with a fake page and hacking group Anonymous allegedly threatening their advertisers in a YouTube video.

It comes as the Australian Communications and Media Authority (ACMA) began talks with 2Day FM and the station launched its own internal inquiry.

The chairman of Austereo has written to the British hospital targeted by 2DayFM's radio prank call.

ACMA said it was "engaging with the station".

"We have not opened an investigation," a spokeswoman said.

Station tried to call hospital before prank aired

In an interview with Melbourne radio station 3AW this morning, Austereo CEO Rhys Holleran said his team had tried to liaise with London's King Edward VII Hospital before airing the controversial conversation.

"We rang them up to discuss what we had recorded. Absolutely (before it went to air). We attempted to contact them on five occasions… because we wanted to speak to them about it," he said.

Communications Minister Stephen Conroy says the independent regulator will look at the hoax call which led to the death of nurse Jacintha Saldahna

"The day prior people took it as being a harmless prank in good humour. If anyone could have foreseen the circumstances… I don’t think anyone could have."

It comes as the Australian Communications and Media Authority (ACMA) is today expected to pick up its investigation into the furore after station management suspended all advertising from 2DayFM until Wednesday.

It's a close call but I reckon that it's reasonably foreseeable that if such a prank succeeded (as it did beyond the DJs' wildest dreams) that the victim would face the sack and that in this economy someone being sacked could lead to them committing suicide. So I really don't think the Pomy press is going too far in its criticism. The Gen Y DJs should, at the very least be sacked, and see what it's like to have to earn a living for a change; say as a nurse at a public hospital.

How come the hospital is not taking responsibility for the lack of security?

@My 2 Bobs: As others have stated you can't seriously compare a joke at work with humiliating someone on a grand scale globally - worse when it's in one of the most serious and often depressing environments possible when people are sick and dying around you. If you think the two can be compared I feel sorry for you.
